41% of construction workers retiring

Construction has a retirement problem, but the real story is a knowledge problem. The headline number — 41% of the current workforce retiring by 2031 — has been floating around the industry for years, and it traces back to NCCER. What makes it feel urgent now is that the labor market is already tight, not hypothetical. Contractors are short on people today, while a big chunk of the most experienced people are moving toward the exit at the same time. ### Where does the 41% number come from? That figure is widely cited across construction groups, consultants, and trade organizations as an NCCER estimate for the current workforce reaching retirement by 2031. It is not a “today’s news” statistic so much as a demographic forecast that has become a planning benchmark. The important part is not whether the exact number ends up 39% or 43%. The important part is that the industry expects a very large share of its experienced workforce to age out within this decade. (nccer.org) ### Why does it feel more serious now? Because the shortage is already here. ABC said in January 2025 that the industry would need 439,000 net new workers that year just to meet demand, and 499,000 in 2026 if spending picks up. AGC’s 2024 workforce survey found 94% of contractors were having trouble filling open positions. So the retirement wave is landing on top of an active hiring gap, not after one. (adp.com) ### Is the workforce really that old? Basically, yes — older than many people assume. BLS puts the median age of construction workers at 42.2 in 2025. CPWR says construction’s average age has been higher than the all-industry average since 2015, and its February 2025 bulletin showed the average age rose from 41.6 in 2011 to 42.1 in 2023. That may not sound dramatic, but across millions of workers it means a lot more people clustered near retirement age. (abc.org) ### Why is this more than a hiring issue? Because jobsites do not run on labor hours alone. They run on tacit knowledge — the stuff that never quite makes it into a drawing set or method statement. A veteran foreman knows which sequence avoids a clash, which crew combination can handle a tricky install, and when a “small” deviation will become rework three weeks later. When those people leave, you do not just lose productivity. You lose judgment. (bls.gov) That is why quality, safety, and commissioning speed can all slip at once. This is partly an inference, but it follows directly from the age and shortage data. ### Why does electrical work get hit hard? Electrical scopes are dense, interdependent, and unforgiving. A bad install can stay invisible until energization, testing, or startup — when fixes are most expensive. That makes “first-time-right” performance heavily dependent on experience in planning, layout, prefabrication, and field coordination. Lose too many experienced leads, and younger crews can still work hard but miss the sequence logic that keeps downstream trades moving. (cpwr.com) That is not unique to electrical, but electrical feels it fast. ### Can firms just replace retirees with more apprentices? Not quickly. Entry-level hiring helps, but it does not instantly recreate supervisory depth. One apprentice can replace hands. An apprentice cannot replace 30 years of pattern recognition on day one. The catch is that many firms need both at once — more beginners to keep labor supply up, and better systems so fewer decisions depend on one veteran superintendent or foreman carrying the whole job in their head. (mckinsey.com) ### So what actually works? The practical answer is boring, which usually means it is real. Shorter lookaheads. Better work packaging. Crew assignments matched to capability, not just availability. More prefabrication where it genuinely reduces field variability. And, crucially, documenting foreman and superintendent know-how before retirement turns it into institutional amnesia. The firms that handle this best will treat knowledge capture like production planning, not like HR paperwork. (constructioncitizen.com) That is an inference from the workforce data, but it is the operational implication. ### Bottom line? The scary part of 41% retiring is not the percentage. It is what walks out with those workers — sequencing instinct, mentorship, and field judgment. Construction can survive a labor shortage. What hurts more is a know-how shortage. (adp.com) (cpwr.com)
